What you think of my set up

Looks like 1.6umole/joule.
Philips rates their bulb in lumens/watt... I would like to compare the efficiency of the two.

Their 315 bulb is rated for 2umole/joule so the 600w is 20% less efficient than their 315. Im betting the philips is another 20% efficient. 2.2-2.6 is my bet.

So currently im using a 600w hps but its too costly so thinking of giving led a go
So im thinking 2 mars hydro ts600 or 1 tsw2000
In my 120x120x180 tent with 4 photos
Cost of the light is a little bit of a prob really need to be under £300
If your in q colder location then led doesnt save much on electric... you'll need heaters

Thats why i still like COB's. because cobs throw a decent bit of heat. Not sure about QB's because i dont have any yet. Might get a small HLG in the future.

Not looking to beat the 600w hps
I no ill not get anywhere near the performance for the budget. Simply put i need to change the cist if running the lights so i can move to led or go down in whats with the hps. Iv herad great things about the mars hydro units thats all

"how many scientists does it take to pick a lightbulb" should be a new saying.
as you know that was a joke but i am a journeyman electrician and in my humble opinion as long as you have the correct spectrum and coverage both types will work also depends a lot on the climate i use HID in the winter and LED in the summer to keep the room temps at 77.7 degrees fairenheit

XLG ballasts and bridgelux gen 2 will murder the 600w hps for around your budget
